Abstract

Background

Evidence on the safety and appropriateness of vaginal birth after caesarean (VBAC) appears clear, but knowledge about women's choice towards this mode of birth is limited.

Aims

To identify variables related to women's decision-making about whether to try for VBAC.

Method and findings

Cross-sectional study was conducted. Feelings of body failure towards the previous birth and the desire to have a vaginal birth were associated with maternal choice of VBAC. Women who perceived a repeated section as being dangerous for them opted for a VBAC (p=0.030). Opinion of women with the same experience and information found online were implicated into maternal decision-making.

Conclusion

This is the first Italian study to confirm that maternal choice is complex and involves many factors. Midwives and obstetricians should strive to provide an evidence-based midwifery care, in order to offer a VBAC as a safe birth option.

Despite the World Health Organization ([WHO], 2015) consensus that rate of caesarean section (c-section) should be between 10%–15%, because higher percentages are not associated with a reduction in maternal and neonatal mortality, that rate has staidly risen in Italy from 11.2% in 1980 to 34.9% in 2015 (Basili et al, 2018).

An important factor contributing to the rising rates of c-sections is a repeated surgical birth following a previous c-section, although the risks are considered higher than with vaginal birth (Tan et al, 2007). In order to promote a reduction of c-section rate, it is essential to prevent primary caesarean birth (American College of Obstetricians and Gynecologists, 2014) and to promote vaginal birth after caesarean (VBAC), supporting women who opt for it (National Institute of Health and Care Excellence [NICE], 2011; Royal College of Obstetricians and Gynaecologists, 2015).

National (Istituto Superiore di Sanità [ISS] and Sistema Nazionale Linee Guida [SNLG], 2010) and international (NICE, 2011) guidelines recommend vaginal birth to the majority of women with a singleton pregnancy of cephalic presentation at 37+0 weeks or beyond who have had a single previous lower segment caesarean delivery with or without a history of previous vaginal birth. Evidence reported that the success rate for women opting VBAC is around 75% (Bais et al, 2001; Landon et al, 2004), increasing to 90% for women who already had a vaginal birth or a VBAC (Gyamfi et al, 2004).

Despite the recommendations and evidence on the high rates of VBAC, Italy has one of the lowest rates of VBAC at 11.3%, with 88.6% of women who had a prior c-section choosing to repeat it (Euro-Peristat Project, 2018). Evidence on the safety and appropriateness of VBAC appears clear, but knowledge about women's choice towards this mode of birth is limited (Lundgren et al, 2012). The NICE (2011) guidelines recommend that decision-making on mode of birth after a c-section should consider maternal preferences and priorities, as well as risks and benefits of both mode of birth. A Cochrane systematic review evaluated any decision support intervention that could affect mother's decision-making on mode of birth after a c-section (Horey et al, 2012). None of the interventions considered appeared to influence women's decision.

Other studies examined which variables are implicated in this choice and highlighted the complexity of factors influencing women's decision-making (Lundgren et al, 2012). Given the limited evidence on this issue and the need to understand the elements that would support women during their choice, we conducted a study with the aim of identifying variables related to women's decision-making about whether to choose VBAC.

Method

Design

Cross-sectional study.

Setting

The research site is an obstetric unit, level two, Italian maternity hospital, with approximately 2 600 births per year and a VBAC rate of 52.3%, as per an internal report conducted by the research setting. Pregnant women who experienced one previous c-section are booked into a dedicated clinic at 34 weeks' gestation. Here, they received evidenced-based information about birth after a previous c-section from an obstetrician.

Women who were looked after by an obstetrician working at the research site or women who get in contact with the research site's clinics with the aim to attempt a VBAC, attended the meeting at 34 weeks. Among them, we selected participants who met the inclusion criteria. At the time of the study, women with a previous c-section could only have obstetrician-led care during pregnancy.

Sample

Through a convenient sampling method, participants were recruited from women with a previous c-section who were booked to attend the meeting at 34 weeks. Exclusion criteria: more than two previous c-sections, previous longitudinal segment c-section; women with other obstetric or medical reasons that would preclude a vaginal birth; women unable to read and speak Italian sufficiently to understand the information leaflet, and to read and complete the questionnaire; women who did not return a signed consent form. The study included 76 women, who were divided into two groups based on their choice about the mode of birth; an elective repeated c-section (ERCS) or a VBAC.

Recruitment

The recruitment process lasted five months, from February to July 2018. Women were approached to participate in the research during the third trimester of pregnancy by the obstetrician involved in their antenatal care.

The obstetricians were informed about the study and were asked to provide the information sheet to the women, where they could find the research midwife's contact details. Otherwise, the women could ask to be phoned back by the researcher. When the researcher could speak with the women, she explained their involvement in the study, asked if they agreed to participate in the study, and if they were available to sign the consent form.

Data collection tools

Data were collected using a questionnaire, developed following a review of the existing literature. Participants completed the questionnaire immediately before the appointment with the obstetrician at 34 weeks. They returned the questionnaire to the researcher as soon as they finished it. The questionnaire contained 38 closed questions and was divided into two sections: information on previous pregnancy and previous c-section; information of current pregnancy.

The questionnaire included items with different response options: six multiple choices questions addressing memories about the type and the reason of the previous c-section; whether they had the perception that the c-section was needed; choice about infant feeding during the previous experience; healthcare suggestion on mode of birth after c-section; maternal wishes on mode of birth.

Five numeric rating scales measured how quickly women recovered from c-section, ranging from ‘very slow’ (=0) to ‘very quick’ (=10), and to evaluate mother's risk perception regarding an ERCS and a VBAC, both on women's and baby's health, ranging from ‘very low’ (=0) to ‘very high’ (=10); 17 responses using a five-point Likert (1932) scale to assess the agreement level with some statements.

These types of questions addressed information received during the previous pregnancy, eg ‘I was well informed about the pregnancy or labour potential complications and when a c-section could be needed’; information regarding the previous experience, eg ‘My partner was involved during the decision-making about c-section’, ‘I got the perception that my body failed to give birth’ or ‘I am satisfied with the previous birth experience’; questions on professional and informal information sources that could influence women's decision-making on mode of birth after c-section, eg ‘My partner influenced my decision on mode of birth’ or ‘The information found online influenced my decision on mode of birth’; maternal expectations, eg ‘Having a VBAC is important to me’. The response categories on the five-point Likert (1932) scales ranged from ‘do not agree at all’ (=1) to ‘totally agree’ (=5).

Socio-demographic variables and outcomes of current labour and birth were collected by the researcher from the medical electronic records and the birth register.

Statistical analysis

Data were analysed using Stata/MP version 15.0. Descriptive analysis of socio-demographic characteristics, previous and current obstetric history, and intrapartum outcomes variables were obtained by means and standard deviations (continuous variables), and by percentages (categorical variables). The five-point Likert scale questions' score was dichotomised between ‘no agreement’ (score from 1–3) and a ‘high agreement’ (score from 4–5) with the statement. The numeric rating scales to evaluate mother's risk perception regarding an ERCS and a VBAC, both on women's and baby's health was also dichotomised between ‘perception of low risk’ (score from 0–6) and ‘perception of high risk’ (score from 7–10).

A descriptive analysis was performed separately on ERCS and VBAC groups. In addition, a comparison between groups was performed using a T-student test for continuous variables and a Chi-Square test for dichotomous variables with a 5% significance level to evaluate the p-values. To improve understanding of non-significant p-values, we calculated the minimum distance between the population average (for continuous variables) or population percentage (for categorical variables), such as the power of the hypothesis testing is equal to 80%. In case of dichotomous variables, the percentage observed into the VBAC group was considered the reference number to calculate the minimum distance.

A logistic regression model was performed to relate variables considered into the questionnaire to women's choice on mode of birth. A p-value (<0.05) was considered statistically significant.

Results

A total of 115 women with a previous c-section were screened for the eligibility criteria (Figure 1). A total of 76 women were included in the study, among them 48 (63.16%) chose a VBAC and 28 (36.84%) opted for a c-section. Table 1 shows socio-demographic variables, previous and current obstetric history according to maternal choice on mode of birth.

A significant difference between groups was found only for the marital status (p=0.001) and the employment status (p=0.005). None of the variables considered in the previous or current obstetric history showed to be significant to this study.

Women's perception on previous c-section according to maternal choice on mode of birth is reported in Table 2. There was no relationship between the type of previous c-section and current maternal choice on mode of birth. The majority of the participants (90.79%) perceived that their previous c-section was needed, therefore there was a clinical reason for it.

VBAC = vaginal birth after caesarean; ERCS = elective repeated caesarean section; c-section = caesarean section; BMI = body mass index

A small number of women, 19.7% (Table 2), expressed their high satisfaction with the previous birth experience with a score between 4–5 (high agreement with the statement into the questionnaire). Among them, women who were satisfied with their previous c-section chose to repeat it. Maternal personal characteristics as the feelings of body failure towards the previous birth (p=0.004) and maternal satisfaction with the previous experience (p=0.008) were two influencing factors of women's choices.

Another interesting variable evaluated into the questionnaire was the lack of control during the previous experience. Although findings did not show significance, 18.4% of women expressed a sense of loss of control during the previous birth. Among them, 22.9% opted for a VBAC, on the contrary only 10.7% planned an ERCS.

Factors related to the current pregnancy according to maternal choice on mode of birth are reported in Table 3. Most participants (82.6%) perceived that an ERCS was recommended by their obstetrician during pregnancy, with a statistically significant difference between the two groups (95.4% vs 60.0%; p=0.000), a higher percentage was observed in the VBAC group. Women with a greater desire to have a vaginal birth and the participants who considered an early bonding and feeding to be important were more likely to choose a VBAC (p=0.000; p=0.035, respectively).

VBA C= vaginal birth after caesarean; ERCS = elective repeated caesarean section; c-section = caesarean section; BMI = body mass index

The four items assessing women's risk perception of both mode of birth in relation to their health and the wellbeing of their baby showed interesting findings. Women perceiving an ERCS as being dangerous for them, more often opted for a VBAC (p=0.030). The three remaining rating scales did not reach significance, however, we could observe that maternal choice on mode of birth followed a trend associated with the risk perception expressed for the baby's health.

When women perceive VBAC to be a risky option for their baby, they more often opt for a ERCS (18.7% vs 32.1%, respectively). On the contrary, women who expressed a high risk for their baby in case of ERCS were more likely to try for a VBAC to avoid another c-section (20.8% vs 7.1%, respectively).

Finally, other factors, such as the opinion of other women with the same birth experience and information found online, appeared to be significantly implicated into maternal decision-making. Participants who reported that these two variables influenced their choice were found only in the VBAC group (women with the same experience: p=0.002; information found online: p=0.003).

Findings emerged from the logistic regression model about factors related to maternal request of VBAC and are reported in Table 4. Women's perception of previous c-section as the feelings of body failure towards the previous birth was an independent factor associated with maternal choice of VBAC (OR= 5.76; CI 95%: 1.175–28.244 in Table 4). Among the variables related to the current pregnancy, the logistic regression model showed that a maternal desire to have a vaginal birth was the only one to remain independently associated with the maternal request of VBAC (OR= 8.82; CI 95%: 2.147–36.205 in Table 4).

Among the 76 participants, 30 (39.5%) women had a spontaneous labour, 13 (17.1%) had an induction of labour and 33 (43.4%) performed an ERCS (Figure 2). Intrapartum outcomes are reported in Table 5, according to mode of onset of labour. No clinical or subclinical uterine ruptures occurred among participants.

Discussion

To our knowledge, this is the first Italian study to confirm that maternal choice of mode of birth after c-section is complex and involves many factors. Items included in the questionnaire were linked to women's socio-demographic characteristics, previous and current obstetric history, women's perception on previous c-section, and current pregnancy experience.

Our findings showed that the clinical aspects of previous c-section (ie previous emergency or elective c-section) were not involved in maternal decision-making, while women's feelings regarding the previous experience played an important role in maternal choice. Moreover, women's desire to have a VBAC could be explained as the maternal willingness to ‘heal’ physically and emotionally from a previous experience (Dahlen and Homer, 2013; Bonzon et al, 2017; Chen et al, 2017). Mothers who express a strong desire to achieve a natural birth view this experience as a significant aspect of their femininity and a major life event for a woman (Phillips et al, 2010).

It is acknowledged that women's childbirth experience could influence future reproductive choices (Gottvall and Waldenström, 2002; Waldenström et al, 2004; Britton, 2006; Larkin et al, 2012). Although our study did not investigate this particular aspect, literature suggests that birth interventions may cause physical and emotional trauma that can have a significant impact on some women (Keedle et al, 2015; Hollander et al, 2017), perhaps in such case, leaving them with a strong wish in attempting a VBAC during a following pregnancy (Dahlen and Homer, 2013; Bonzon et al, 2017; Chen et al, 2017).

Our research showed that women with a lower birth satisfaction in regard to the previous experience prefer to attempt a VBAC. Although our results did not reach significance, there is a trend towards a relationship between a high perception of loss of control and a lower birth satisfaction as amply demonstrated by the literature (Bayes et al, 2008; Brodrick, 2008; Goldbort, 2009; DeLuca and Lobel, 2014; Hildingsson, 2015; Hollander et al, 2017; Downe et al, 2018).

A feeling to have lost control over the previous birth process and a previous negative birth experience could potentially be implicated with maternal desire to have a vaginal birth which, in this study, is the only independent factor influencing maternal decision-making to opt for a VBAC. The same could be observed when considering the variable linked to the previous infant feeding experience.

This was not as relevant as the maternal desire to live the opportunity of an early bonding and feeding with the baby during this pregnancy. This study finds the research setting, such as the majority of the Italian maternity units, do not provide skin-to-skin contact when a c-section occurs. The absence of this important practice could lead participants to choose a VBAC in order to meet their baby immediately after birth.

Our study is the first exploring women's risk perception towards two different mode of birth after a previous c-section (VBAC vs ERCS), both with respect to the mother's and baby's health. The four numeric rating scales adopted to measure maternal risk perception, namely the risk of VBAC for the mother; the risk of VBAC for the baby; the risk of ERCS for the mother; the risk of ERCS for the baby, showed that the participants feel there could be a risk in both mode of birth for themselves and their baby.

Women expressed to feel a higher risk for their wellbeing when compared to the risk perceived for their baby in relation to both the VBAC and the ERCS. It is reasonable to assume that this risk perception could be due to thoughts and feelings women have regarding their previous child at home, as all participants were multiparous.

Women who perceived an ERCS as a riskier option for their health were more likely to opt for a VBAC—this remained the factor independently associated with maternal choice of mode of birth. Although findings are not significant, it seems data showed that there is a sort of ‘protection’ toward the baby. When participants perceive a high risk for either the VBAC or ERCS in relation to the baby's health, they tend to choose the birth option they feel safer for the baby.

Although, attitude and support from healthcare professionals, continuity of care, and information received during pregnancy – especially when evidence-based – could play a significant role in maternal decision to opt for a VBAC, our study showed different results (McGrath et al, 2010; Flannagan and Reid, 2012; Lundgren et al, 2012; Dahlen and Homer, 2013; Martin et al, 2014; Nilsson et al, 2015).

Even though participants were not influenced by their obstetrician's opinion, more than 82% of them reported that their doctor recommended to have an ERCS which is in contrast to the evidence (Dahlen and Homer, 2013; Nilsson et al, 2015). Previous studies (Godden et al, 2012; Lundgren et al, 2012; Dahlen and Homer, 2013) reported that often the communication with caregivers could be highly risk-oriented, leading to a lack of trust expressed by the woman with feelings of decisional conflicts and insecurity, generating fear in women who want to make the right choice for them (Godden et al, 2012; Lundgren et al, 2012; Dahlen and Homer, 2013).

This could be the reason why women choose the research site as their birth place, as it is known as a maternity unit in favour of VBAC. Participants most likely want to seek professional information about the mode of birth after a c-section in a supportive environment (Godden et al, 2012; Lundgren et al, 2012; Dahlen and Homer, 2013).

In contrast with the prior evidence, family and friends' opinion were not implicated in maternal choice (Lundgren et al, 2012; Dexter et al, 2014; Scaffidi et al, 2014; Nilsson et al, 2015; Munro et al, 2017). Women rated as important the experience of other women (ISS and SNLG, 2010; Konheim-Kalkstein et al, 2014) and information found online (Frost et al, 2009; Dexter et al, 2014), both these factors in accordance with other research, appeared to be implicated into maternal decision-making.

An unsupportive system could lead women who would prefer a VBAC to seek information about it themselves by, for example, searching the online and by meeting women who had experienced VBAC (Godden et al, 2012; Dahlen and Homer, 2013; Nilsson et al, 2015). Although this information sources lead women to opt for a VBAC offering them the opportunity to share their experiences, our findings invite healthcare professionals to recognise VBAC as a valid birth choice. Evidence-based information should be provided during counselling and women should be supported in their choice with the aim to offer a positive experience of birth (WHO, 2018).

The small sample size didn't allow to observe a high number of significant data, nonetheless we could confirm the findings of previous studies regarding the factors involved in maternal decision-making on mode of birth after a c-section. The questionnaire adopted is not without limitation. It consists of closed questions which could evoke ideas that the respondents would not otherwise have or it could comprise answers that would not be the first choice for the participants.

Further research is recommended to strengthen the results in this study; this is especially important when considering the Italian context where there is a high-risk culture surrounding childbirth (Rota et al, 2017; Euro-Peristat Project, 2018) and where very few women with a previous c-section are supported and informed to opt for a VBAC.

From our findings, the majority of women perceived their previous c-section as being appropriate, however, maternal desire to experience a vaginal birth remains their focus. This could be lived as a redemption from a previous feeling of failure. Data showed that skin-to-skin contact appeared to be relevant for the mothers in this study.

Women should make their choice based on evidence-based information that recommend to offer a VBAC when there are no other risk factors to preclude a vaginal birth, rather than on a previous negative experience. Midwives and obstetricians should strive to provide an evidence-based midwifery care to every women and child without differences based on previous mode of birth. Furthermore, healthcare professional should improve their individualised counselling in order to offer a VBAC as a safe birth option for women and babies.

Key points

  • Women's feelings of failure regarding the previous birth and the maternal desire to have a vaginal birth were independent factors associated with maternal choice of vaginal birth after caesarean (VBAC). This could be explained as the maternal willingness to ‘heal’ physically and emotionally from a previous experience
  • Maternal choice of VBAC is related to the desire to experience an early bond with the baby during the pregnancy
  • It seems that women are aware only about risks related to an elective repeated caesarean c-section (ERCS) for themselves, without considering that there are disadvantages also for their baby
  • Despite participants not being influenced by their obstetrician's opinion, more than 82% of them reported that their doctor recommended having an ERCS, which is in contrast to the evidence
  • CPD reflective questions

  • Could previous childbirth experience influence future reproductive choices?
  • Could a previous caesarean birth experience be implicated into women's choice for future births?
  • Do midwives provide evidence-based information to women, in order to support them in their choice?
  • Are women aware of potential risks and benefits of a repeated caesarean section for both themselves and their baby?
  • How could healthcare professionals support women and family during their decision-making process?
